Lupinus argenteus Pursh.
var. pariflorus (Nutt.) Hitchc.
Silvery lupine is a perennial from twelve to thirty inches tall. Older plants usually have several stems from a heavy taproot. Dense hairs on stems and leaves give the plant a silvery appearance. Leaves are about two inches long, the tips divided into six to eight narrow leaflets that radiate like fingers from a hand. Above the leaves, blue flowers form in narrow, curved clusters up to eight inches long. Inch-long pods (legumes) containing dark yellow seeds develop later. Nuttall reported this plant on the plains of the Rocky Mountains toward the Oregon. Found on the Fort Hall Indian Reservation.
Caution: Portions of this plant or poisonous.
